I have a link between SPA3102 and SPA 2102. SPA 3102 is connected to PSTN line and SPA 2102 is connected to SPA 3102 via ethernet. Analogue phone in DTMF mode is connected to SPA 2102. The problem is after tearing down the call and put the headset on-hook SPA 3102 hold the PSTN line for 3-4 seconds! Is there somehow to change this time out? I would be happy if SPA 3102 tear-down the PSTN line immediately after closing the headset.
I ran some tests on my SPA3102 and couldn't get any delays. How do you discern that the PSTN Line does not disconnect promptly?

Does the SPA2102 delay sending the BYE to the SPA3102?
Does the SPA3102 delay putting the FXO port back on hook when it receives the BYE?
Does the PSTN line voltage immediately restore to about +/- 49v when the FXO port goes back on hook?
You can run a sip debug trace with times annotated to look at the BYE's and FXO off and on hook. The following syslog program has an option to include the received time by starting the program with the /t option.... slogsrv.exe -t
